Sprint Spark TDD two 20 MHz LTE-CA

For Band 26, the FCC license in the USA limits maximum frequency to 824 MHz, thereby allowing two 5x5 MHz (up / down) channels in the old Nextel ESMR (tower transmit 859-869 MHz).
In many areas Sprint only has enough ESMR spectrum for one 5x5 MHz LTE band 26 channel.
